Followed getting started guide on Readme. Went to run and got these errors during the build.
Cloned v2.52.17

5 errors

I think it must have something to do with the @immutable annotation as that is a custom annotation definition.

I just changed my project to import SweetBlue as a module and Im now getting even more errors:

Note: I also tried just cloning this repo directly and trying to run the integration module and i get the exact same errors.

FYI in your project build.gradle file you need to swap jcenter() and google() so that google() comes first. Also i had to add google() as a dependency under allprojects.repositories. Gradle would not even sync for me until i did these things. This SO post led me to this conclusion:
https://stackoverflow.com/questions/50786296/failed-to-resolve-common-open-file-gradle-build

buildscript {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'commons-codec:commons-codec:1.8'
        //classpath 'org.apache.ant:ant-jsch:1.7.1', 'jsch:jsch:0.1.29'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
}

Its possible that I am using a newer version of Android Studio that you guys are. Perhaps that is why things are not working for me. Listed below is the version I am using:
